The only thing that stops me is the fact that I barely use it in the first place. Knock on wood, there's not that much at stake for me. Maybe. Still, Facebook has become the intense, flaming nucleus of the social-network-crazed cluelessness that's running rampant on the Internet.
It will be interesting to see if they can pull out of this steepening dive in time, or if they will crash in fiery self-destruction. If Facebook does recover, I'm not sure I'll ever trust them. But will I trust them enough to keep the accounts open and continue to (carefully) use the service? That's the question.
